This makes me jump fifteen years behind (or so, I do not remember times), at the time of the great push so the Internet prefers:
Random J. User <firstname.lastname@example.org>
It is more reasonable to always give the real name, optionally followed by an email, that to consider that the real name is a mere comment for the email address. Oh, I know some hackers who praise themselves as login names or dream having positronic brains :-), but most of us are humans before anything else!
Could the PEP be reformulated, at least, for leaving the choice opened?
Yes. The rule will be Name first, Email second. We won't convert all 200 existing PEPs to that format yet, but if someone with commit privileges wants to volunteer, be our guest.
